KiwiSDR is a software-defined radio (SDR) covering shortwave, the longwave & AM broadcast bands, various utility stations, and amateur radio transmissions, world-wide, in the spectrum from 10 kHz to 30 MHz. The KiwiSDR is a custom circuit board (cape) you connect to the BeagleBone Green or BeagleBone Black computer. You simply add an antenna, power supply and network connection. The KiwiSDR is available in two versions: the cape alone and a more complete version including BBG, enclosure and GPS antenna. Both versions include software supplied on a micro-SD card.

An HTML5-capable browser and internet connection will let you listen to a public KiwiSDR anywhere in the world. Up to four people can listen simultaneously to one radio — each listener tunes independently.

Hi Ron. If you purchased from Seeed please email techsupport@seeed.cc to get a replacement. Otherwise contact the distributor you purchased from. There seem to have been a bunch of BBGs produced with Ethernet PHY failures. John (support@kiwisdr.com)

VA3ROM, sorry I've only seen your question just now (July 27). I don't get a notification for these unfortunately. There _should_ have been a printed "quick start" instruction sheet in the box with enclosure assembly information. You can find it online here: http://kiwisdr.com/quickstart/quickstart.pdf Please email support@kiwisdr.com with any questions. Best regards, John, ZL/KF6VO, KiwiSDR

Sorry, I am only seeing this question now, one month later. Actually, the SE4150L is the GPS front-end chip used on the Kiwi board. For a compatible GPS antenna you want one that has an SMA-M connector, works at 3.3V, at least 27 dB of gain and no more than 3m cable length if it is using small diameter coax to avoid excessive signal loss. One example is the Abracon APAMP-111 available from Mouser in the USA. Please see the kiwisdr.com website for more details. Regards, John, KiwiSDR
